Number and Number Relations: Lesson 3

Visual models support young mathematicians as they deepen their fractional number sense in this elementary math lesson. Using fraction circle manipulatives, children explore basic unit fractions as they develop the fundamental...

Need a number line? Here are four number lines ranging from zero to twenty.

This short problem with representing fractions on a number line is more than meets the eye. Labeled only with the numbers zero and 1/4, a number line is used to locate the fraction 2/3. A solution can be found in multiple ways, but young...

Understanding place value is a basic mathematics skill. This Khan Academy video shows students how to write the number 14,897 in the expanded form. He explains that the 7 in the ones place is the same as 7x1, the 9 in the tens place is...

Translate fractions of an area into fractions on a number line with the third of a four-video series. A clear description of how to determine the value of each tick mark on a number line begins the lesson, clarifying the concept of...

Explicit and direct instruction is great for children who are struggling in math; it is also great for introducing a new topic or idea. Help your learners understand exactly what it means to identify an equivalent fraction on a number...

The big question: Is eight eighths equivalent to one? Use a number line to show how to express fractions that are equivalent to one. The concept is introduced first through review and then with visual representations that support lesson...

Number lines are great visual tools that can be used to teach a wide range of math topics. The final video of this series models how to use number lines when solving subtraction problems using the counting up strategy. Pause the video...

Add to the toolbox of young mathematicians by teaching them to compare fractions using number lines. The final video in this series models the process for labeling and comparing fractions on number lines with multiple supporting...

Step by step, two examples of creating number lines are explained through a series of animations. One is meant to watch at home, the second can be viewed in class, and there is a third tab with two sample problems to try. This skill,...
